STEERING APPARATUS FOR BOATS.

Patented April 17, 1906.

Application filed July 3, 1905. Serial No. 268,219.

To all whom it Huey concern:

Be it known that I, CHARLES W. Pos'r, a citizen of the United States,residing at Zion City, in the county of Lake and State of Illinois, haveinvented certain new and useful Improvements in a Combined Propellingand Steering Apparatus for Boats, of which the following, When taken inconnection with the drawings accompanying and forming a part hereof, isa full and complete description sufflcient to enable those skilled inthe art to which it pertains to understand, make, and use the same.

This invention is particularly designed to provide means for propellingsmall boats in any desired direction and in shallow water, although itis equally well adapted to propel large boats in any desired directionin deep water.

I have illustrated the machine embodying this invention in the drawingsreferred to, in which Figure 1 is a side elevation of the apparatus, andFig. 2 is a vertical section of the apparatus.

A reference-letter applied to designate a given part is used to indicatesuch part throughout both the figures of the drawings wherever the sameappears.

A is the shell or casing of the apparatus, anda is a flange by means ofwhich the shell is attached to the bottom of a boat, on the insidethereof, with the part 0. extending through the bottom of such boat tounderneath the bottom thereof.

a is a screw-threaded aperture in shell A, to which is attached awater-pipe from a pump or other water-forcing apparatus, by means ofwhich water can be forced into shell A.

B is a rotatable plug in shell A. Plug B extends above'shell A, andsteering-wheel C is rigidly attached thereto. Plug B is provided withshoulders D E, the shoulder D resting on a corresponding shoulder in thelower end of shell A and shoulder E, positioned to receive thereon thecorresponding shoulder in cap F of shell A. Cap F is screwthreaded, asat f, such screw-threads engaging with like screw threads at the upperend of shell A.

G is packing in shell A adjacent to cap F.

The lower end of the plug B is provided with passageway H, suchpassage-way being curved and contracted, as at h, at its lower end andat its upper end communicating with the chamber I in shell A throughapertures J J.

As will be seen on observing Fig. 2 of the drawings, when water isforced into the chamber I throughthe aperture a such water will flowthrough the apertures J J into passageway H and out therefrom throughaperture h in a substantially horizontal plane. By turning the plugB bymeans of steering-Wheel C the direction of the stream flowing fromaperture it will be changed.

The boat will be moved by the flow of water from the aperture it intothe body of water in which the boat floats, and by the turning of theplug B in a proper manner the boat will be guided in any desireddirection.

Having thus described my invention and the construction of an apparatusembodying the same and the manner of operation there of, what I claim asnew, and desire to secure by Letters Patent, is

The combination of a shell provided with a passage-way therethrough, ashoulder at the lower end of the passage-Way and such passage-wayenlarged to form a chamber, and such shell provided with an aperturetherethrough communicating with the chamber, a plug rotatably mounted inthe shell and extending below it, such plug provided With a shouldercorresponding with and resting on the shoulder in the shell, and suchplug provided with a passage-way communicating with the chamber in theshell and with the water below the shell, the discharge of such passageway directing the Water flowing therethrough in a substantiallyhorizontal plane, and a steering-wheel attached to the rotatable plug,substantially as described.
